Argent performs comprehensive server availability checks; in particular the Argent Guardian provides the ability to scan the listening TCP/IP Ports many products use for communication, specifically:

• TCP Port 25 (SMTP)
• TCP Port 80 (WWW)
• TCP Port 389 (LDAP)
• TCP Port 3268 (Global Catalogue)

Note: The above ports are merely common examples — Argent can ensure that any TCP port is open.
